Be it known thatv JI, RONALD ELrsoNy a citizen of the United States, Richland county, State of South Carolina, have invented certain new and useful Improvements in Attachments for Smoothing-Irons, 'of which ation. l p

' The object of this invention isto provide means adapted for use in conjunction with the ordinary household smoothing iron', whereby the latter is rendered more efficient rwhen being usedin theJ'usual manner, and which enables the operator to convert the same intolan electrical iron quickly and conveniently by the further a 7ditionof an elec- Brieily stated, the invention consists in a heat retaining casing of a" size and shape suitable for receiving within its walls, the body portion of an ordinary hand smoothing iron, and which may an electrical heating unitf which, when connected to y a source of electrical power heats the iron continuously and enables it to be used as an electrical iron as though built as one in the CAMPBELL,

Vfirst instance.. If .desired the casing may be used with the iron alone, without the electrical heating unit, and in this case it serves to protect the hand of the user against the .heat radiating from the body of the iron,`

of heating element from that shown in Fig. 5" and drawn to a smaller scale.

The casing 10'may be lformed in any oneI of a number of different ways`and may be' of any one of a variety of. materials, but preferably 1t is pressed or stamped from sheet metal, lwhereby the advantages of cheapness, strength and lightness of construction are realized. The casing has an opening in its rear end through which the 1ron 11 rand elther form lof heating elementv 12l or 13 may be yinserted or withdrawn, `and this opening is normally closed by a door 14 pivoted at its lower edge to the rear edgelof the bottom wall of the casing. A slidingA latch 15, clearly shown in Fig. 3, normally holds the door in closed position, the end of the latch extending when in locking position through an opening in the side wall of the casing. Y The iron 10 has the usual handle 16 rigvidly secured thereto and the casing is necessarily slotted, as at 17 to enable the iron f sulating covering, to .hinder the transfer of heat from the iron to the work. v

The electrical'heating devices adapted to beused with the casing above described lare preferably flat, as illustrated, and conform yto the shape ofthe iron. As, in some cases,

the heating unit is most advantageously placed beneath the iron and inother cases, above the iron depending largely upon the character of work to be done, two forms ofA such. heating elements are provided. The electrical unit 12,'is adapted to be placed beneath the iron while the u nit 13, which is provided with a slot toreceive the uprights of the iron handle is suitable for use on'the upper side of thel iron. The units` 'themselves may be of any desired specic construction, and the wall thickness and2 size and Aarrangement of coils designed in various ways, depending upon the character of work to be done and the size of the iron.

Sockets 12', l2 and 13', 13 respectively are provided in the rear portion of the electrical devices 12 and 13 to receive the conducting plugs of an electrical connector, such as illustrated in Figs. 1 and 2 to connect the coils of the heating devices to a source of electric current.I To prevent rattling dueto movement of the iron or heating device within the casing, set screws 21, 21 are provided which extend downwardly through threaded openings in the top of the casing. These set screws are operable from without and their lower ends bear down on the iron or heating unit, whichever is uppermost to prevent movement, whenever they are tightened. f

'Ihe casing may be used with or without the heating unit. If used with a `smoothing iron alone, it serves chiefly asa heat retainer for the hot'iron which it contains, preventing wastage of heat through radia- 'tion and protecting at the same time the -hand of 'the user.

heating devices are used, the'ordinary 1ron` When both casing and 1s converted into an electric iron at slight expense. In case the heating element becomes damaged 4it may be withdrawn for repairs or replacement and the iron and protective casing used together until the broken part has been repaired or a new heating element obtained. It is not necessary, when the heating element becomes damaged, to employ the services of an electrician, the

unskilled iron user being able to insert anew heating unit obtained from the manufacturer whenever necessary. It is obvious that changes may be made in the arrangement and construction of the parts of the invention, and I do not, therefore, limit myself to the embodiment described and illustrated.

Having thus described the invention what. is claimed as newand desired to be secured by Letters Patent is: c

1. In a device of the class described, a

` casing openable to receive the body portion of a smoothing iron, the handle thereof extendingrwithout the casing and said casing an abestps lining, for the purpose set forth.

, 4. In a device of the class described, in combination, aA flat electrical heating element adapted to be attached to a smoothing-r iron and a casing openable to receive the v.iron and heating element and closable to` incase them and hold them in fixed position.

5. In a device of the class described, a casing openable to receive the body portion of a smoothing iron having a handle, the casing being provided with a slot through which the handle of the iron may extend.

6. In a device of the class described, a casing openable to receive the body portion of a smoothing iron havingva handle, the.

casing being provided with a slot through which the handle of the iron may extend, and means for closing the slot after the iron has been inserted in the casing, to retain the heat therein.

7. In a device of the class described, a casing openable to receive the body portion of a smoothing iron having a handle, the casing beingyp'rovided with a slot through which the handle of the iron maylextend, a

removable and replaceable plate for closing the slot after the iron hasbeen inserted and means for retaining said plate in closing position, for the purpose set forth.

8. In a deviceof the class described, in .l

combination, a casing openable to receive the body portion of a smoothing iron, and closable to incase .the iron, and an electrical heating element in said casing and located between the bottom of the iron and the bottom of the casing.
